  • Miners: Where to be in a world of low commodity prices?

    Where do miners sit after the commodity crash? BHP is a miner with a very serious hobby in oil and gas, but it makes its living from iron ore and copper. That hobby has started to look too much of a luxury since the oil price collapsed last year. On Wednesday it announced cuts to its US shale oil effort, only a few years after entering the space. It wants to reduce exposure to the the areas it cannot control. But what of iron ore, BHP's key product accounting for easily half of operating profits?

In that note, we characterized KAZ Minerals of Kazakhstan as a high cost producer. The company begs to differ, and they sent us the following counter-argument:

  • UK residential property: get out or double down?

    UK house prices rose 7 per cent last year, according to Nationwide. Shares in housebuilders Persimmon and Barratt are up by over 10 per cent. Nice profits all round, then. Time to get out while the going is good, or double down in the hope that not even higher interest rates will damage the long term growth story? Join us at midday UK time for a live discussion.
